Application filed J'une 7, 1912. Serial No. 702,216.

To all whom it may concern: I

Be it known that I, FRANK E. MCLEAN, a citizen of the United States ofAmerica, residing at Muskegon, in the county of Muskegon and State ofMichigan, have invented certain new and useful Improvements in Cabinetsfor Type-Writing, Adding, Print ing, or other Analogous Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

My invention relates to improvements in cabinets for typewriting,adding, printing or other analogous machines and itsobject is to providethe same with improved means for movably supporting the machine, toprovide improved means for counterbalancing the device and for lockingthe same 1n various positions, and to provide the device with variousnew and useful features hereinafter more fully described andparticularly pointed out in the claims.

My invention consists essentially of a suitable case, a verticallymovable frame or elevator arranged within the case, a longitudinallymovable table mounted on the elevator to carry the machine, said tablebeing adapted to be projected outside of the case, balancing andsupporting means for raising and lowering the elevator, preferablyconsisting of a spring actuated shaft, supporting means carrying theelevator and operated by the shaft, whereby the machine table andelevator are counterbalanced and easily moved, means for holding theparts in open or closed positions, and in various features ofconstruction and arrangement as will more fully appear by reference tothe accompanying drawings, in which:

Figure 1 is a longitudinal vertical section of a device embodying myinvention shown in closed position; Fig. 2 the same shown in openposition with portions broken away, Fig. 3 a horizontal section show ngthe table in plan view and in closed posltion; Fig. 4: the same in openposition and partially broken away; Fig. 5 an enlarged detail invertical section showing a. portion of the supporting mechanism for theelevator; Fig. 6 a plan view of the same shown in horizontal section inthe plane of the axis of the shafts; Fig. 7 a detail of the worm andgear for adjusting the tension of the spring Specification of LettersPatent.

Patented Apr. it, ibis.

Fig. 8 a modification of the device shown in vertical section, withparts broken away Fig. 9 a detail in vertical section shown at rightangles to Fig. 8; Fig. 10 a detail in elevation of the rear rack andpinion; and

Fig. 11 the same of one of the front rack and pinions.

Like numbers refer to like parts in all of the figures.

1 represents a case of any convenient construction the case shown beingadapted to form one member of a sectional pedestal to a desk whichobviously may be otherwise constructed as preferred. 2 a front door tothe same adapted to swing open out of the way of the table.

3 is a horizontally disposed rectangular frame constituting an elevatorto carry the table 3 upon the front part of which the typewriter orother machine is supported. This table extends inward beyond the machinea sufficient distance so that when ex tended the machine will besuitably located outside of the case and the table extend suitablywithin the case and overlap the elevator. The inner end of the table isheld down by underrunning rollers 25 traversing the side rails of theelevator frame. At each side of the front end of the elevator and themiddle of the rear of the same are vertically disposed racks 1 fixed onthe inner side of the case. Extending beneath the middle of the elevatorfrom front to rear is a rotative shaft 5 mounted in suitable bearingsfixed on the elevator. Coiled around this shaft is a spring 6 one end ofwhich is secured to a collar 13 fixed on the shaft and the other endsecured to a worm gear 11 journaled on the shaft. This gear is held by aworm 12 and by turning this worm with a suitable key the tension of thespring 6 may be adjusted at pleasure. This spring tends to rotate theshaft in a direction suitable for raising the elevator and when properlytensioned balances the movable parts of the device and the machinethereon so that the same moves up or down freely.

The supporting means for the elevator consists preferably of pinions 7engaging the racks 4, the pinions 7 being mounted on the respective endsof a transverse shaft 10' and the rear end of the shaft 5. The shaftsare connected by bevel gears 8 and 9 whereby all of the pinions rotatesimultaneously and in the same direction thus traversing the racks beingeach formed of sheet metal folded in channel shape, one flange of whichis extended inward toward the respective shaft and provided with teethto form the rack i to engage the respective pinion.

The table is preferably mounted on rollers to run freely to and frolongitudinally on the elevator and is provided near the rear with theunder-running rollers 25 to hold the rear end down-when the table isprojected The table is also provided with a longitudinal groove 28 and aguide pin 2-1 is fixed in the elevator and slidably engages this groove,whereby outward from the elevator.

the table is properly guided to and fro upon the elevator.

To hold the device in lowered or raised position a guide strip 17 isprovided at each side of the front opening of the case projecting intothe path of the table. When the table is lowered this guide strip isabove the front corner of the same and holds the table and elevator inlowered position, a friction roller 18 preferably being used at the endof the guide strip to insure free running of the "table. The table isprovided at a proper place in each side with a recess 22 adapted toreceive the respective guide strip 17 when the table is moved out theproper distance, which is limited by a stop 21 011 the bottom of thetable to engage the front member of the elevator. The elevator and tablecan then be freely raised to the top of the case as shown in Fig. 2 andby moving the table inward by about the width of the guide strip thesame will be under the table and hold it in elevated position. A stop 21is provided to prevent further inward movement of the table when raised.be securely held in the proper position for use and properly supported.The bracket 19 on the door being swung under the table further adds tothe supporting means.

In the modified form shown in Figs. 8 and 9, the racks and pinions atthe front, the bevel gears, and the transverse shaft, are displaced by acheaper structure which serves the same purposes, consisting of awinding drum 28 on the shaft 5 in place of the bevel gear 8 two steeltapes 26 oppositely wound on this drum and extending oppositely beneathsupporting rollers 27 on the elevator, and thence upward at each side ofthe same, being secured at the upper ends to the sides of the case nearthe top thereof. The drum 28 is of such diameter as to wind the steeltapes at about the same rate that the pinion lowered.

.movement of the table to its The typewriter will thus at all times andthe elevator'has no tendency to rise at this end.
